What pH and water activity levels do bacteria grow?
pH levels vary among bacterial species. For example; acidophillic bacteria grow best at low pH. While alkalophiles grow better at alkaline (high) pH. Most bacteria grow best at high aw (>0.90). While few bacterial species such as xerophiles grow best at an aw of 0.6-0.7
What kind of pH does bacteria prefer?
pH levels vary among bacterial species. For example; acidophillic bacteria grow best at low pH. While alkalophiles grow better at alkaline (high) pH. Most bacteria grow best at high aw (>0.90). While few bacterial species such as xerophiles grow best at an aw of 0.6-0.7
What is the pH of salmonella?
Salmonella is a type of bacteria. It requires a pH of 4.4 to 9.0 (prefers 6.5 to 7.5) to grow successfully.
Where is the best places for bacteria to grow?
Its not a fact that all bacteria find the body an ideal place to grow in. Bacteria are host-specific and substrate specific. They grow in places which are conducive for their growth. Bacteria which dwell within the body find it to be inhabitable because the body provides optimum conditions of pH and temperature, for enzyme activity, protein action and other metabolic activities. Also, living cells are a source for nourishment for such bacteria.
Why plants and animals are pH sensitive?
Yes, plants grow best in soils with certain pH values, though optimal pH varies with the plant. Animals usually need to maintain an internal pH close to 7.
What pH and water activity (aw) levels do bacteria grow best?

What is the importance of pH levels?
* Blood: blood must be kept at a certain pH to ensure the haemoglobin can bond to oxygen. Otherwise, the formation of carbonic acid by dissolved carbon dioxide can cause anaemia and oxygen deprivation. * Plants: many plants require a certain soil pH, otherwise they are unable to grow. * Bacteria: most bacteria have a certain range of pH which they grow best in. Outside this range, growth can be stunted or even prevented entirely. * Enzymes: Like bacteria, some enzymes work best in certain pH ranges, but will almost cease entirely when not.

Why would lemon juice be an effective way to kill bacteria?
Most bacteria as well as our cells work best at certain pH levels. Lemon juice has a pH of around 2. Our body has a pH around 7.4. Most bacteria prefer a pH of 7.
What is the pH for asparagus?
Asparagus plants grow best in soil it a pH lever of 6.0-6.8.
Bacteria grow in what condition best?
Warm and moist.
What conditions does bacteria live best?
bacteria lives in moist places and can grow in a shower
